Enabling the GTP-u Echo Request Procedure

The existing CLI (Command Line Interface) in gtpu-service is used to enable the GTP-u Echo request procedure.


configure 
   gtpu-service service_name 
      echo-interval seconds 
      echo-retransmission-timeout seconds 
      max-retransmissions num 
      path-failure detection-policy gtp echo 
      end 

NOTES:

  • gtpu-service service_name : Creates a GTP-u service enters the GTP-u Service Configuration Mode for the current context. service_name specifies the name of the GTP-u service.

  • echo-interval seconds : Configures the rate at which GTP v1-u echo packets are sent. seconds specifies the number of seconds between the sending of a GTP-uv1 echo packet. It must be an integer in the range of 60–3600.

  • echo-retransmission-timeout seconds : Configures the timeout for GTP-u echo message retransmissions for this service. seconds specifies the echo retransmission timeout, in seconds, for the GTP-u service. It must be an integer in the range of 1–20. The default value is 5.

  • max-retransmissions num : Configures the maximum retry limit for GTP-u echo retransmissions. num specifies the number of GTP-u echo message retransmissions allowed before triggering a path failure error condition. It must be an integer in the range of 0–15.

  • path-failure detection-policy gtp echo : Configures a path failure detection policy on GTP-u echo messages that have been retransmitted the maximum number of retry times. gtp echo sets the detection policy to detect a failure upon reaching the maximum number of GTP-u echo message retransmissions.

The following is a sample configuration for enabling GTP-u Echo request procedure.

configure
   gtpu-service n3-gtpu-service
   echo-interval 60
   echo-retransmission-timeout 5
   max-retransmissions 5
   path-failure detection-policy gtp echo
   end
